Shark’S PointerS ONLINE Advanced Slam Bidding Techniques Mark Aquino 5-22-20 “Easley Misunderstood” Last week, we highlighted some common Blackwood misunderstandings This week we’ll pick up where we left off and review more advanced slam bidding techniques. Just 2 warnings before we get started... #1) Try to avoid artificial bids #2) Have easy-to-remember agreements Easley Blackwood (1903-1992) Advanced Slam Bidding Techniques Today we’ll discuss the following: “Minorwood” Interference Over Blackwood Modified Gerber Keycard After Partner’s Weak 2’s and 3-Level Preempts Void Showing Responses to Blackwood “Baze” “MinorWooD” Using 4NT for RKCB over a minor often gets the bidding to an untenably high level. Many use the other minor as RKCB. Others use the suit above as RKCB. They often do this when hearts is trumps – they use 4S as RKCB. (“Kickback”) I don’t do either, because many times the Q bid is helpful, the artificial bid invites opps to make lead directional doubles – and many other accidents occur. I prefer what is called “Minorwood” – a bid of 4 of our known minor is RKCB. e.g. 1♦-2♦* (inverted raise) -4♦* (RKCB) Responses are progressive (once again I use 1430), so 4♥ =1or4 4♠ =0or3 4N=2w/oQ 5 ♣ =2w/Q i Can Be BoUGht… BUT I HATE KICKBACK!! ESCHEW OBFUSCATION!!! KISS (Keep It Simple Stupid!) Which leads to our next topic…. Interference over Blackwood This comes up once every 10 years or so, but when it does it is very important you don’t forget DOPE = KISS ROPE is your agreement! made from HEMP “Shark Standard” is DOPE/ROPE at all levels There is no “GoSPel aCCorDinG to Saint Shark”! • Last week, I showed a disastrous result when my partner and I had a misunderstanding in a slam auction. • Beware – The bids we’ll discuss today may have different interpretations. • Make sure you and your partner have the same understanding! Modified Gerber There are times when you want to know only about Aces After partner opens 1NT or 2NT: A jump to 4♣ asks “how many aces?” “Shark Standard” combines Gerber and RKCB (1430) 4 ♦= 1 or 4 4 ♥=0 or 3 4 ♠=2 with a minimum 4N= 2 with a MAXIMUM Helps remembering the responses – and it adds valuable info! Beware of Shark Infested Waters! rkCB after Partner’S Weak 2 If partner opens a weak 2, you may want to look for a slam- without going beyond game level. Partner is limited to the number of keycards he can hold. Try this mnemonic: 0 1 1 2 2 0 = No keycards 1 = 1 without the Queen 1 = 1 with the Queen 2 = 2 without the Queen 2 = 2 keycards with the Queen of trumps NOTE! 2♥-4♣ -4♥= (1 w/o) 2♠-4♣-4♠=(1 with) Grand National Teams Championship Flight Semifinal July 20, 2019 Las Vegas NABC d25 VS d17 NORTH ♠ Q109 Neither Vul Dlr N N E S W Pat McDevitt ♥ AK1098 2H P 4C P ♦ 65 4S P 5H All Pass Sherri Weinstock WEST ♣ 9 87 Fred Gitelman EAST ♠ J876532 ♠ K4 ♥ 2 ♥ Q76 ♦ 2 ♦ AJ10987 ♣ J432 SOUTH ♠ A ♣ 105 Opening Lead ♦A Mark Aquino ♥ J543 Down 1 MINUS 100 ♦ KQ43 ♣ AKQ6 RKCB After 3 Level Preempts After 3♦ / 3♥ / 3♠ 4 ♣ = RCKB After 3♣ 4♣ is to play After 3♣ 4 ♦ = RKCB In all cases 0 1 1 2 2 NOTE! 3♥- 4 ♣- 4 ♥ = 1 without the Q 3 ♠ - 4 ♣- 4 ♠ = 1 with the Q Void showing responses to Blackwood Some may recall this hand from an earlier “Shark’s Pointers” (“Hurry Up or Wait”) ♠ KQ10 In response to 4NT (RKCB), in order to show a void ♥ Q10987 and the number of keycards, here are the rules: ♦ AQ6 5NT = Void with an EVEN # of keycards ♣ AQ 6 of non trump suit = Void in that suit w/ ODD # 6 of trump suit = Void in a suit higher w/ ODD# ♠ Void ♥ AKJ32 Q: After 1H-2N*-3S*-4N – what do you bid? ♦ KJ32 A: (In “Shark Standard”) 5NT is correct bid ♣ J432 WHAT TO DO WITH THESE HANDS? 1NT-2C-2H-? 1NT-2C-2S-? ♠ AQ107 ♠ AQ107 ♥ K10 ♥ K10 ♦ K102 ♦ K102 ♣ KJ98 ♣ KJ98 WHAT TO DO WITH THESE HANDS? 1NT-2C-2H-? 1NT-2C-2S-? ♠ AQ107 ♠ AQ107 ♥ K10 ♥ K10 ♦ K102 ♦ K102 ♣ KJ98 ♣ KJ98 We agreed 4NT Anyway we could ask for Keycards?
